Times Cited Count:4 Percentile:49.92(Materials Science, Multidisciplinary)High-entropy alloys are characteristic of extensive atomic occupational disorder on high-symmetric lattices, differing from traditional alloys. Here, we investigate magnetic and thermal transport properties of the prototype face-centered-cubic high-entropy alloy CrMnFeCoNi by combining physical properties measurements and neutron scattering. Direct-current (dc) and alternating-current (ac) magnetizations measurements indicate a mictomagnetic behavior with coexisting antiferromagnetic and ferromagnetic interactions in the entire temperature region and three anomalies are found at about 80, 50, and 20 K, which are related to the paramagnetic to antiferromagnetic transition, the antiferromagnetic to ferromagnetic transition, and the spin freezing, respectively. The electrical and thermal conductivities are significantly reduced compared to Ni and the temperature dependence of lattice thermal conductivity exhibits a glass-like plateau. Inelastic neutron scattering measurements suggest weak anharmonicity so that the thermal transport is expected to be dominated by the defect scattering.

Times Cited Count:27 Percentile:90.23(Multidisciplinary Sciences)In high-performance thermoelectric materials, there are two main low thermal conductivity mechanisms: the phonon anharmonic and phonon scattering resulting from the dynamic disorder, which have been successfully revealed by inelastic neutron scattering. Using neutron scattering and ab initio calculations, we report here a mechanism of static local structure distortion combined with phonon-anharmonic-induced ultralow lattice thermal conductivity in -MgAgSb. Since the transverse acoustic phonons are almost fully scattered by the intrinsic distorted rocksalt sublattice in this compound, the heat is mainly transported by the longitudinal acoustic phonons. The ultralow thermal conductivity in
-MgAgSb is attributed to its atomic dynamics being altered by the structure distortion, which presents a possible microscopic route to enhance the performance of similar thermoelectric materials.

We show that the ATS should have important impact on our understanding of the nature of some newly observed threshold states. Discussions on how to distinguish the ATS phenomena from genuine dynamic pole structures are presented.

Times Cited Count:3 Percentile:18.27(Physics, Condensed Matter)Defects in electron-irradiated (3, 6 MeV) ZnO substrates were investigated using optical detection of magnetic response (ODMR). The shallow donor and the Zn vacancy were detected. In addition, several ODMR centers with S= were also observed. Among these, LU3 and LU4 shows a behavior as recombination centers. After annealing at 400
C, both LU3 and LU4 still remain in ZnO substrates.

Times Cited Count:18 Percentile:57.41(Physics, Applied)Optical detection of magnetic resonance (ODMR) was performed to investigate defects in ZnO irradiated with 3 MeV electrons at room temperature. As a result, the Zn vacancy and some other centers were detected by ODMR. The Zn vacancy and two other centers whish are labeled as LU3 and LU4, were also commonly observed in different types of as-grown ZnO. Therefore, it can be concluded that the both LU3 and LU4 might be related to intrinsic defects, and they act as dominating recombination centers in irradiated and as-grown ZnO.
